| 摘 要： | 采用6种不同处理方式对五叶草莓进行保鲜处理,以蒸馏水处理组为对照,测定贮藏过程中五叶草莓果实感官性状、失重率、可溶性固形物、可滴定酸、VC及丙二醛含量等指标的变化,研究不同处理方式对其贮藏保鲜效果的影响.结果表明:6种处理组五叶草莓果实保鲜效果均显著优于对照组,其中2％柠檬酸+3％CaCl2处理、1％壳聚糖处理和2％柠檬酸+2％VC 3种处理组的五叶草莓果实感官性状维持最好,且1％壳聚糖处理组还在减少可溶性固形物、可滴定酸、VC损失及丙二醛产生等方面显著优于上述两种处理组.综合各项指标考虑,五叶草莓采用1％壳聚糖处理保鲜效果最好,保鲜期可延长至6d左右,具有一定的市场应用前景.

| Abstract: | In this experiment, six different treatment methods were executed for Fragaria pentaphylla preservation, the changes of sensory properties, weight loss rates, soluble solid, titratable acids, vitamin C and malondialdehyde contents were determined during the storage process, aiming to investigate the effects of different treatments on storage and fresh-keeping effects of Fragaria pentaphylla employing distilled water treatment group as control. Results showed that the preservation effects of six treatment groups were obviously superior to that of control group, and the treatments of 2% citric acid+3% CaCl2, 1% chitosan and 2% citric acid+2% vitamin C maintained the best sensory properties of strawberry fruits, furthermore, the treatment of 1% chitosan could also significantly decrease the loss of soluble solids, titratable acids, vitamin C and the generation of malondialdehyde and so on, compared with the above two treatment groups. Taking all the indicators into consideration, the treatment of 1% chitosan showed the best fresh-keeping effects on Fragaria pentaphylla, and the preservation period could be extended to about 6 days, which exhibited certain market application prospect. |
